What kind of fertilizer is good for tea tree base fertilizer (base fertilizer application method)

The role of tea tree base fertilizer

As a perennial evergreen crop, tea trees have obvious characteristics of nutrient storage and reuse. The above-ground part stops growing, but the underground part continues to absorb nutrients. In addition to maintaining basic metabolism during the winter, most of the absorbed nutrients are stored in the root system, which becomes the material basis for the sprouting of new shoots in the second year, playing a decisive role in the early growth and fatness of spring tea.

Tea tree fertilizer selection

To improve the fertility of the soil for tea trees, you can apply garbage fertilizer, straw, ferns, and farmyard manure after deep plowing the soil. Add lime and compound fertilizer to each hole. The base fertilizer should be applied deeply, but not too close to the roots. It is enough to be about 15 cm away from the bottom of the seedling roots. Then fill the soil and cover the top with the original base soil to prevent grass growth.

How to use tea tree base fertilizer

The base fertilizer for tea trees should be applied in early to mid-October, which can improve the fertility of the soil and enhance the cold resistance of the plants.

The amount of base fertilizer used in conventional tea gardens is 15,000-20,000 kg of compost plus 250-400 kg of phosphate rock fertilizer per mu, which should be applied after being piled for 5-10 days.

If it is a densely planted fast-growing tea garden, the amount of base fertilizer should be increased, that is, the amount of fertilizer per mu should be increased to 25,000-30,000 kg, and 250-400 kg of phosphate rock powder should be added to the compost, and applied after piling for 5-10 days. In this way, better fertilization effects can be achieved.
